Hospital Ward

There were 100 patients in a road trauma hospital. Some of the patients had only one leg. Half the rest had no legs. In total how many legs did the 100 patients have?

Answer

100. The group with one leg each averages one leg per person. The rest are split into 2 equal groups. One group has no legs, so the other group must have 2 legs each, meaning these 2 groups average one leg per patient. Therefore, overall, the average is one leg per patient, therefore there is a total of 100 legs.Hide
